What a Step Seal Is
Step Seal is a single-directional,high-performance sealing component widely used in hydraulic cylinder piston rod seals.Step Seal achieves lower friction and better dynamic response characteristics than Glyd Ring through its unique stepped design,especially in high-pressure applications.TurconR StepsealR 2K is a single-acting,O-Ring energized rod seal for dynamic applications.The seal incorporates a number of innovative features that enhance sealing efficiency with better extrusion resistance giving superior leakage control and allowing larger hardware tolerance.
Performance in High-Pressure Conditions
These seals operate at high pressure without any risk of blow-by effect.They remain highly extrusion-proof and pressure-resistant.Resistant to high pressure (up to 720 bar for dynamic seals),high and low temperatures, wear,and impact.Long Service Life follows from these traits.The inherent excellent friction characteristics,wear resistance stand out.Very good abrasion resistance,low friction,stick-slip free running come standard.
Materials and Design Features
Common construction uses a PTFE slide ring with step cut and an O-ring energizer High wear and extrusion resistance build into the design.Materials include bronze-filled PTFE for the ring and NBR or FKM for the energizer.This combination delivers low friction with no stick-slip,minimal break-out force and high wear resistance.
Why These Solutions Are Cost-Effective
Typical Applications
These seals suit heavy-duty hydraulic cylinders,excavators,construction machinery,and systems requiring reliable performance under extreme pressure.
